超声引导下多平面鼻唇沟矫正术

目标: Primary Objective: * Assess efficacy and safety of ultrasound-guided multi-plane HA filler in nasolabial fold correction. Secondary Objectives: * Evaluate fold depth reduction * Assess aesthetic improvement and facial symmetry * Monitor adverse events and patient satisfaction 介绍: Nasolabial folds (NLFs) are a prominent feature of facial aging. Traditional HA filler injection carries risk of vascular compromise and inconsistent results due to anatomical variability. 材料 / 方法: Twenty-five patients received deep supraperiosteal and superficial subcutaneous HA injections in the NLF region under real-time ultrasound guidance. Arteries and veins were mapped prior to injection. Outcomes included fold depth reduction, contour improvement, patient satisfaction, and adverse events over 12 weeks. 结果: NLF softening achieved in 92% of patients, with improved contour and facial symmetry. Minor ecchymosis occurred in 15%; no intravascular events were observed. Ultrasound allowed precise filler placement, enhancing safety and predictability. 总结: Ultrasound-guided multi-plane HA filler injection is a safe, effective, and predictable method for nasolabial fold correction. This technique ensures smooth contouring, reduces vascular risk, and achieves natural aesthetic outcomes.
